During rainy days, the maximum speed on urban roads is 30 kilometers per hour, as detailed below: 1. Urban roads with a central divider: speed limit of 50 km/h; rural roads with obstacles: 70 km/h. 2. Urban roads without a divider: generally limited to 30 km/h; rural roads without a divider: 40 km/h. 3. Urban roads without a divider at 40 km/h: different from those with a divider, should be calculated at 30 or 40 km/h. Precautions for driving in the rain are as follows: 1. Reduce speed and drive slowly: In severe weather, strictly control your driving speed to allow yourself time to react. Rain reduces tire traction, so maintain low speeds, use second or third gear, and keep speed under 30 or 40 km/h. Driving fast on highways with thin water layers can cause hydroplaning, leading to loss of control. When stopping, decelerate about 100 meters in advance to give following vehicles time to react. 2. Ensure clear visibility: Rain obstructs vision, increasing accident risks. Turn on wipers promptly and adjust their speed according to rain intensity for clear visibility. In dim weather, use low beams, fog lights, and marker lights. If fogging occurs, use the air conditioner to clear it. Keep mirrors clear; install rain shields, use rain repellents, or activate mirror heating if needed. 3. Water crossing techniques: Before crossing underpasses or flooded areas, check water depth. Use low gear, maintain steady speed, avoid gear changes, stops, or high speeds. On muddy roads, follow the tracks of the vehicle ahead.

The speed limit on urban roads during rainy days is not fixed and should be adjusted flexibly based on road conditions. Generally, urban road speed limit signs indicate 40-60 km/h, but I recommend reducing it to 20-30 km/h in the rain due to the higher risk of road slippage and significantly extended braking distance. Last time I drove a bit too fast in the city during rain and almost hit the car in front, which made me realize that slowing down is crucial. Remember, during rainy days, don't just focus on speed—also turn on your wipers and low beams to ensure clear visibility. Maintain a following distance at least twice as long as usual to allow for reaction time, so even if you encounter standing water, you can brake safely. Make it a habit to check tire wear before driving in the rain to ensure sufficient traction. In short, safety comes first—better to be a few minutes late than to take unnecessary risks.

As a long-time city driver, I've noticed that rainy-day speed regulations vary by region, but the general requirement is to drive at least 50% slower than in dry conditions. For example, in major cities like Beijing, main roads typically have a speed limit of 60 km/h, so I usually keep it under 30 km/h in the rain. When visibility is poor during heavy rain, even driving at 20 km/h is acceptable. The key is to follow traffic signs, such as checking roadside speed limit signs or listening to traffic radio warnings. Don't overlook the details: turn on headlights for better visibility and avoid sharp turns, as wet roads increase the risk of skidding. From my experience, planning routes in advance during rainy days, avoiding congested areas, and minimizing sudden acceleration or braking not only saves fuel but also prevents accidents. Developing these habits makes city driving much safer.

After years of driving, I believe it's best to maintain a speed of 20-30 km/h on urban roads during rainy days. Wet road surfaces make braking difficult in emergencies if driving too fast. Once, I drove at 40 km/h in heavy rain downtown and nearly rear-ended another car, which taught me the importance of slowing down. I recommend staying observant: check rainfall intensity and visibility, adjusting accordingly. Don't forget to turn on wipers and headlights while keeping a safe distance. Never rush when driving in the rain - slow and steady wins the race.
